Definitions

  • the invention relates to a printing unit for typical use in a price-labelling device or the like.
  • each setting wheel has guided around it an endless type band, on the external side of which are arranged printing types and possibly also reading types associated with the printing types, while driving projections are arranged on the inside of the said band and these projections engage in tooth gaps of the setting wheel. It is also known to provide the setting wheels on their circumference with printing types and possibly also reading types, so that the setting wheels simultaneously also form printing type wheels.
  • the setting shaft is provided with tangentially encircling grooves corresponding to the number of the setting wheels, which grooves have spacings from one another which correspond to the widths of the setting wheels and in which engages a resilient detent member, which is arranged in a fixed position on the housing of the printing unit and is formed by a ball, which is guided in a bore of the housing and which is under the action of a small helical spring.
  • This known detent or latching device has the disadvantage that the manufacture thereof is costly and that the fitting thereof is complicated and time-consuming. Furthermore, this printing unit has the disadvantage that, with printing units of equal width but a different arrangement of wider or narrower printing type bands or printing type wheels, it is necessary to have setting shafts which are adapted to the arrangement of the wider or narrower bands or wheels.
  • the printing type wheels provided with the appropriate types have on their periphery recesses which are engaged by projections or teeth of the setting wheels. So as to produce the axial latching of the setting shaft, the latter has fixed thereon so as to be axially immovable a pointer which engages over the circumference of the setting wheels, the said pointer comprising at its free end a detent member projecting at right-angles to the setting shaft and the said detent engages in the latching recesses of an easily replaceable detent rail.
  • the said printing unit is capable of being adapted to the actual arrangement of printing type wheels or printing type bands of different widths.
  • a disadvantage as regards this printing unit is that the detent member and the detent recesses co-operating therewith are spaced from the setting shaft, so that bending moments have to be transmitted by the pointer. As a consequence, the pointer has to be constructed and guided in a suitable manner for absorbing loads.
  • the detent recesses are formed by bevelled surfaces on the edges, which are arranged on the bosses of the setting wheels.
  • the bevelled edge surfaces of two setting wheels arranged in juxtaposition form an encircling groove, which is engaged by resilient detent members arranged on the setting shaft.
  • This printing unit has the advantage that the setting wheels themselves form tangentially encircling grooves, of which the axial spacings correspond to the respective widths of the setting wheels and of the printing type bands which are guided over said wheels.
  • this printing unit has the disadvantage that the grooves formed by edge bevelled surfaces can only be of relatively small cross-section and these grooves are interrupted by the internal toothing of the setting wheels, which toothing co-operates with the driver element of the setting shaft.
  • the detent device of the respective arrangement can be adapted to printing type bands or printing type wheels of different widths. No additional parts are necessary for the detent or latching device.
  • An easy and simple positioning of the driver element in the axial direction is obtained if the detent recesses have axially an undulatory or sinusoidal profile.
  • the detent recesses When the pin is rigidly fixed, the detent recesses have to be formed as tangentially encircling grooves.
  • the cross-section of the longitudinal recess and the cross-section of the pin are not circular and the pin is held to be rotatable about its longitudinal axis on the housing wall and that they are provided with at least two different rows or series of detent recesses.
  • the printing unit can be fitted in a double, triple or quadruple manner and differently with printing type bands or wheels of different widths.
  • the possible variants as regards the printing unit can be doubled if the series of detent recesses are arranged asymmetrically in relation to the end bearing surfaces of the pin and if the pin is at will capable of being secured at one or the other end on the housing wall.
  • FIG. 1 is a sectional view of the printing unit.
  • FIG. 2 is a side elevation of the printing unit, with the side wall of the housing removed.
  • FIG. 3 is a plan view (partly in section) of an illustrative setting shaft for use in the printing unit of FIG. 1.
  • FIG. 4 is a sectional view of the setting shaft.
  • FIG. 5 is a front view of the setting shaft.
  • FIG. 6 is a plan view of an illustrative pin for use in the printing unit of FIG. 1.
  • FIG. 7 is a side elevation of the pin.
  • FIG. 8 is a front elevation of the pin.
  • FIG. 9 is a view along the section line IX--IX of FIG. 7.
  • the printing unit according to FIGS. 1 and 2 comprises five type bands 1, which carry printing types 2 on their external surfaces and which comprise driving projections 3 on their internal surfaces.
  • the driving projections 3 engage in tooth gaps 4, which are arranged on the circumference of setting wheels 5.
  • the setting wheels 5 are rotatably mounted between the housing walls 6 and 7 in a trough 8.
  • the printing types 2 can be adjusted by means of a setting shaft 9, which comprises at its outer end a setting knob 10 and which, at its inner, free end, carries a driver element 11 formed as a pinion, which can be brought into mesh with an internal toothing 12 of the setting wheels 5.
  • the setting shaft 9 is arranged to be rotatable and axially displaceable in a plain bearing 13 arranged on the housing wall 6.
  • the setting shaft 9 has a central longitudinal recess 14, in which engages a pin 15, which is held by a push-in or inserted detent or latching member 16 on the housing wall 7.
  • the pin 15 is provided with latching recesses 17, which are arranged at intervals on the pin 15 and which correspond to the spacings of the setting wheels 5 from one another.
  • a resilient detent or latch member 18 Arranged on the free end of the setting shaft 9 is a resilient detent or latch member 18, which is formed by a tongue 19.
  • the tongue 19 is connected in one piece with the setting shaft 9, consisting of synthetic plastics material, and is formed by axially extending notches 20 (see FIG. 3).
  • a pointer 21 and then setting knob 10 are pushed on to that part of the setting shaft 9 which projects from the housing of the printing unit.
  • the setting shaft 9 is rotatable in relation to the pointer 21, while the setting knob 10 is connected so as to be fast in rotation with the setting shaft 9 by means of the non-circular end region 22.
  • the driver element 11 and the resilient detent or latching member 18 are arranged on the free end of the setting shaft 9.
  • the driver element 11 and latch 18 may be arranged in the same plane extending at right-angles to the axis of rotation of the setting shaft 9, or they may also be offset axially to some extent relatively thereto.
  • the cross-section of the longitudinal recess 14 has two flattened sides 23.
  • the tongue 19 with the resilient detent or latching member 18 is arranged on one of these flattened sides.
  • FIGS. 8 and 9 show that the cross-section of the pin 15 corresponds to the cross-section of the longitudinal recess 14.
  • the pin 15 is thus incapable of being rotated in the longitudinal recess 14.
  • Arranged on the flat sides of the pin 15 are different rows of latching recesses 17 and 17'. If the latch or detent member 18 of the setting shaft 9 co-operates with the latching recesses 17 which can be seen from FIGS. 6 and 7, the printing unit is equipped with six printing type bands 1 and setting wheels 5 of substantially the same width. However, if the detent or latching member 18 of the setting shaft 9 co-operates with the detent recesses 17' which can be seen from FIG. 7, then the printing mechanism or unit is equipped with eight printing type bands 1 and setting wheels 5 of substantially the same width.
  • the detent recesses 17, 17' are arranged at different spacings.
  • detent recesses 17, 17' are arranged asymmetrically or axially offset with respect to the end bearing surfaces 24, 24' of the pin 15.
  • Arranged on the two ends of the pin 15 are resilient insertion latches or detent members 16, 16', so that the sequence as regards the different widths of printing types can be changed, if the pin 15 is inserted, rotated through 180°, into the housing wall 6.
